Example: If LTFT-Lo is at a constant +5%, add +5% to the 50 Hz slider in the airflow table. If the LTFT-Lo is at a constant +12.5% and STFT is at +13%, add +26% to the 50 Hz slider in the airflow table. Repeat until you are happy.
Example: If STFT’s are bouncing between +14% and +16%, add +15% to the 150 Hz slider in the airflow table. Repeat until you are happy.
Example: If the fuel trim is at a constant +7%, add +7% to the 250 Hz slider in the airflow table. Repeat until you are happy.
Example: You make a pull and you get the following results:
Note: The following calculation method provides a crude approximation of the needed adjustment and depends on the estimated and measured A/F ratio values being somewhere near 10:1. Use ECMLink's correctly calculated WBFactor value instead.
A simple formula for calculating this is:
(est a/f - WB02) * (-10) = airflow adjustment amount.
MAFRaw (hz) 800
A/F Ratio 9.5
Adjustment + 25%
(9.5 - 12.0) * (- 10)
(-2.5) * (- 10)
